Hey Friend,
That sucks to hear. You are young yet, you can beat this. At risk of sounding like a snake-oil salesman. You should look into a Green/Vegan diet. I'm talking about wheat grass and kale. Mix it up, juice it, doesn't taste all that bad.
I don't think you should worry about your co-workers premiums. It's all money, honestly who can't go without an extra $50-300 a month or whatever. People spend what they have usually, it'll all work it. It'll all work out.
It's called Insurance for a reason. Don't worry about the Insurance companies. Focus on getting well, and staying stress-free as possible.
Good luck my friend.
